ELECTRIC SYSTEM.

To all whom it may concern: Be it known that I, MARK C. C0sGnAY, -2. citizen of the United States,- and a resident of Port Clinton, in the county of Ottawa and State of Ohio, have invented a certain new and useful Electric System; .and -I do hereby declare the following tube a, vfull, clear, and exact description of the invention, such as will enable others-'skilled'in theeert to which itnppertains make and use the same, reference being had to the acrompenying drawings and to the characters of reference marked thereon, which form a part of. this specification.

My invention relates to electric systems, and it has for itsobject to provide a unitary buttery system for feeding electricity consuming devices,-'which is co-ordinated with :i bettery charging system. It further provides regulating devices which control the current supplied to the system, and which intercontrol the charging devices and the current that is consumed so as to suppl} the current either-t0 the battery or to the consuming system, eccordin to the watts consumed by the system. AFso by my invention is provided a storage battery and :rgencrator system wherein the' current will l'iesupplied by the battery or generator, or both. to n, consuming system of translating devices, depending upon the wattage consumed or trensleted in the translating devices.

The invention may be contained in many forms of systems and arrangements of parts usable for different purposes, all-of which come within the purview of my claims hereinafter appended. To show the practicebi-lity 0% my invention, I have selected an electric system of current supply, consunr ing and controlling devices, as an example of the systems and constructions containing the invention, and shall describe them here inafter. .The system and the devices selected are illustrated in the accompanying drawings. 7

The switch .10 may :nlso be provided with fuses 11 of the. formwell known .inthe art. Then it isdesired to connect the consuming system. with the controlling devices and the {Oll ICB orrsources of current supply, .the switch .10 ,is closed: I I x Thegstora e battery current,in supplying the system avingthetrenslating. devicfi passes through emain line safety switch 15 illustrated; in Fig. ,2, to which the battery is connectedhy the wire 16 and through an ampere-hour meter or coulomb meter 17, the ampere-hour meter being connected :to

the switch 15 by means of the wire 18. The umperehour meter is of the type known commercially as the Sangamo ampere-hour meter. As isvwell known it lltlfijflflfilfifihllcal means for causing r0tation ofthe pointer and contact 19. As the current passes from the battery through the amperehourmeter 17, the pointer rotates counterclockwise and 7 passes from the fully charged"or"1 0O% battery charged point, on which the contact gtl is located, to the 85% battery charged point, on which the contact 621 is located. I? h e meter 1'! is connected to'the' automatic intercontrolling switch 22- ilhistriitedin Fig.6, by the wire 23. It passes through the series coil 24 of the automatic"intercontrolling switch "and through the wire- 25 which conneots the'coil-24 withthe main line 4 ofthe consuming system. Thencewfthe current passes through the translating devices to the lines 5-or'6 or to both' of thelines. From the line 5it returns through hvire"26to the master switdhQI-Fillus'tratd 'inTig. I 7, thence to the wire '28 "which completes the circuit-to the storage battery '1, and 'ffrom the line 6 it passes through thelline 29 to the battery "1;" 3

The main line safety switch '15; "Illustrated in F igs.*2,3, 4 and 5, is suitably supported on-a switch-board 30 icmred mi slate or suitable "composite insulating material by means of the -pivot=pin""31 which is supported 'in a housing '32.- The swliih lm 33 extends from within' the housing and; ls provide'tl withleaf contacts '34a'nd with-spring pressed carbon contacts The "contacts 34 and 35 are connected to'a 'cross a'rn'1 36 which is connected to"'or formedintegral with the switch 'a'rm' 33. Thesprings'37 which carry the carbon contaJctsB5 are so supported and tensioned that in' elosing the switch, the carbon contacts are elosed'hefore the metal leaf contactsare closed, and are opened subsequent "to the opening of the metal leaf'contacts. The carbon contacts thus break the circuit later and 'takeany arcing that may be'produeed by'reasonof the opening of the=switch 15. "'The'switch armfwhen closed, is located in a vertical position -so that when it is released; the springs 37 and the leaf contacts throw the switch arm forward. "The leaf'bontacts 34 make contact with fixed metallic contacts 39, and the carbon contacts '35 make contact with 'ooacting fixed' carb'on contacts '40, which are secured to the contacts 39. The ou'terend of the arm 33 is provided with'a disk armature 45, which islocatedabove a cup or iron-clad In et 46 which'is also secured tothe'switch card 305' Ihe arma-' tu re '45 is provided'with afhandle'or knob 4-7, whereby the switch 'a rm 33 and the armature 45 may be-easily manipulated.

The magnet 46 is provided with two coils,-oue is the coil "50 which is so conthe battery, the'coil 51 will be automatically connected in the circuit, and permit the switch 15 to be opened by the springs 38. The coil 51 is wound in the direction opposite to that in which the coil 50 iswound, or thekconnectionsriare such that when the circuit of the coil 51 is completed, it passes in a direction opposite to that in which the current "passes through the coil 50 to cause substantial de-energization of the magnet and thus relieves the armature 45, which under-the operation of thespring 29,-causes the switch' 15 to'open. This prevents any 'furtherconsumption of electricity stored in the battery 1.-

The coil -50 is connected to the binding post 53 of the meter'l'i, and when the switch 15 is clo'sed -to allow the current to pass through'the wires 16 and 18'tothe meter 17, and to the binding P681153, line 49, coil 50, line 47, line 29 to the battery 1, the magnet becomes energized and holds the switch 15 closed. 1 l hecoil 51 is connected to the meter 17 by-meansof the wire 48. The meter 17- is 'provi'ded-witha battery zero point having the contact '52, to which the wire 48 is connected. The zero point is the danger point of the discharge of the=battery. If the needle 19 should pass the'85% battery charged pointas it passes counterclockwise around the dial of' the meter, while the battery is 105 discharged, and reachesthe substantial zero point 52, a circuit is completed from the meter 17 through the binding post 53, pointer 19 "to the contact point 52, the kick or release coil 51, back to the storage bat- 110 tery 1. This causes the switch 15 to be opened and the flow of the current discontinues.

The needle 19, during the discharge from the 100% battery charged point 20, passes 115 over the contact 21 located at the 85% battery charged point, whereupon the circuit i completed from the battery through the wires 16 and 18, the pointer 19, contact 21, thence it passes through the wire 55 to the 120 automatic iutercontrolling switch 22 and through a coil 56, wire 57, wire 29, to the storage battery 1." Meantime, the current is also passing through the wires 16 and 18, the meter '17'and the series coil 24 to the 125 consuming system. The coil 56 is thus af fected by the electro-motive force of thebattery 1, while the "coil 24 is afi'ected by the value of the current, that is, its amperage. The two coils 24 and-56, operating'together, 1'30 operate the automatic intercontrolling switch. If the switch 10 is open, the coil 56 alone will loperate the switch 22 when the'circuit is completed between 'thepointer 19 and the contact 21. Also, if the current consumed is large enough, the coil 24, alone,

will operate the switch 22. When the battery is charged, the pointer 19 completes a circuit through the coil 59 which counter; acts the coil 24, as hereinafter'described.

T he switch 22 is supported by means of brackets or legs 60. The switch is'provided with an inverted cup or cylinder 61 in which are located the coils 24, 56 and 59. The switch is also providedwith a central pole 62, which extends through the coils. The pole 62 is suitably clamped in the bottom of the inverted cylinder 61. Its upper end extends through an opening formed in the bottom of the cylinder 61 and is secured in positi'on by means of the nut 63'. The lower end of the pole 62 is provided with a disk 64, of non-magnetic material, which closes the lower end of the cylinder 61. The disk 64 is Secured in position by means ofa'nut 65 which'is' threaded onthe lower end of thepole- 62.- The pole 62 is hollow, forming a sleeve in'which is located a rod which extends through the pole 62. The

upper end of the rod 70 is provided with a nut 71, which is threaded on the rod-70 and forms'a'n adjustablestopi The lower end of the rod is secured to a cup armature 75, in whichyis located a coil 76. The cup armatureis closed by means of a disk 77 of nonmagnetic material. The disk 77 is secured in position between a bushing 78 and a nut 79. The nut 79 is threaded on the central pole of the iron-clad magnet which is thus formed. The edges of the cups 7 Sand 61 have substantially the same diameters and are located" in opposing relation withrespect toea'ch other. On top of the cu p or cylinder 61is located a pair of spring contacts 85 and 86 having platinum points 87 They are supported andseparated by insulating blocks-88 which are secured -to the top of the cup' or cylinder 61. The free endso'f the elastic" contacts-85 and '86 normally rest against theanvil 89. The-anvil 89, having an upwardlyextending ridge 90, operates to-open the spring contacts when they aie released. 'The' upper end of the rod 70 is provided with an insulating point 91. When the-rod 70 is raised by the magnetization produced in the cup 61 by the coil' 24, or the coils 2/1 and 56, the point 91 is pressed against the contact 86, which in turn closes the platinum points 87 and completes the circuit through the contacts '85 and 86. This will complete thecircuit to the masterswitchand start the engine and generator to recharge the hattery as de scribed hereinafter. They will operate until the pointer contactreaches the contact 20,

whereupon the circuit will be completed to the coil 59.

The coil 59 is wound in a direction opposite to that in which the coils 24 and 56 are wound, or is so connected in the circuit that the current passes through the coil 59 in a direction opposite to that in which it passes through the coils 24 and 56, so that coaction of the coil 59 and the weight of the armature 75 will overcome the freezing action of the magnetic materials of which the cups or cylinders 61 and 75 are composed, and open the switch 22. It being connected to the 1009 battery charged point 20 of the meter 17, so that when the pointer 19makes ontact with the contact 20 located on the 100% battery charged point. the circuit will be completed from the positive side of the hattery and generator 3, to the pointer19, and through the line 95, the kick or release coil 59, and through the line 96 to the master switch 27, thence it is comp'letedto the battery 1. 3'

To secure accurate magnetic effect, a resistance coil 97 is connected' in 'serieswith the coil 59, which may beudjusted' dnring the assembling of the switch-board to obtain the desired resultsinthe'operation of the kick or release coil 59, Also, the series or current coil 24 is connected to a shunt 'i'esistance coil'98 for the urp'o'se o'f securing the "desired magnetice ect of'the 24. The resistance of the coil98 is'va'ried accord ing to the specified load that the system is to carry. and also according to 'the cpndr tionsand operations of the automatic intercontrolling switch 22.

The coil 76, of the armature 755s also'a shunt connected coil. Itis connected to'the positive terminal of the ,atter'y' through the lines 16 and 18,'themeter 17 and line ltlO and by lines 57 and 29, to the negative ter: minal.

' The contacts 85 and gtijarefalsb connected in a branch ofjthe circuit froni themeter 17 which is connected totliepositiveteminal of the storage battery through thef'lin'es16 and 18. The contact 86 is connected througl' the'line 105 to the meter 1I,' whi1e the contact 85' isconnected to the'coil' 166*of1the master switch. The coil'106 i's connected to the negative terminal of the storage Battery 1 through the line 28. -Wlien the cbiitacts 85 and 86'are closed, the magnet of the master' switchis energized by the'coil 106,'-and causes the operation of 'the'm'aster' switch.

The switch 1.01 is located in the branched circuit having the coil 76, the'contacts '85 and 86 and the coil 106. an'din operation is kept closed.

The master switch 27, illustrated in Figs; 7, 8 and 9, is also provided'with an iron-clad magnet 110 having the shell' 111 and the movahle'core 112. The coil 106 is inserted in the shell in thc manner well known in the iio iis

art. The core 112 maybe surrounded by a bushing 113 of non-magnetic material. The movable core 112 may also be provided with a guide pm 114, likewise formed of non magnetic material The movable core 112 is provided with a rod 115 which forms a binding, rod for securing the contacts and insulating blocks to the .,core 112. The switch is provided with the leaf spring contacts 116, .117, 118 and 119, and With the carbonicontacts 120 and 12'1'which complete the circuitto the fixed contacts 122, 123, 124, 125,126, 127 and 128, the contacts 122 to 126 inclusive-being provided with coacting carbon blocks 130, with-which the/movable contacts make contact. Theyare .set into recesses formed in the contacts 122 to 126 inelusive in any suitableway.

The pin will operate asa guideto the core and movable contacts.

A cross-bar or strip 140 is also secured to theend of the Erod- 115, .by;,- means ofthe clamp,nuts 137. ;Thecross-har is provided withopenings through which rods 141 and i142 extend. .The lower ends of therods are provided with washers 143=and,pins 144 for holding the washers in position; Compression'spri-ngs 145 are ,locatedon the'rods 142 andiyieldingly push the core 112'out of-the magnetllO when. it is de-enengized. The rods 141 and 142'are threadedat their upper ends .and- .extend through openings and bosses 146' located in the upper'end'of the case-containing the contacts, Thumb nuts 147mm, threaded onthe rods 141 and 142, and consequently, theitension-of the springs ma-yihe adjusted by the thumb nuts 147. When the coil is deenergized, the-circuit is completed across-the fixed contacts 124 and 125, and across the .contacts 127 and 128. When the core is pulled downbymagnetization of :the magnet, the circuit is broken between the contacts 124 and 125, and 127-and the-lines 16and 18, the instrument 17, lines 10 0, 105, contacts and S6, and through the line 107, thecoil 106 of the master switch, line 28 to..the;battery 1, the circuit through the contactS,-124, 125, and also the circuit through the contacts 127 and 128 are opened, while the circuit through the contacts .124 and 126, andgthe circuit through the contacts 122 and 123 .are closed.

'When the connection between the contacts 122;;Jld ,123 is completed, the current passes from the meter 17 which is connected to the positive side of .the battery through the lines 16.and 18 to the shunt wound generator 3,'through the instrument 155 and the line-1,50,,the generator 3, the line 151, the contacts122,,and 123, and the line 28 to the negatiue ,sideof thebattery. This causes rotationof the armature of the generator aI 1(l-tur,ns,the., hat oi the engine 2. The magnero is alspmotated andthe short circuit of;the .magneto,;whicli is completed through theicontacts ;.12 7,and 128,being opened, will cause thesparkingpf the plugs of the engine 2.

The instrument 10:) in the circuit of the genenatorecontrplsithe switch 15. The coil 51of theiswi'tch 15 is connected not only to the zero battery charged point 52 of the instrument 17 by the line 48, but it is also connected to the point 156 of a similar instrument 155 which is provided with a poiuter157 having an adjustable stop 158.

n theoperatiomofythe instrument 155, the pointer 157' will. be turned by theicurrent passingthrough .-the instrument clockwise, and'if suflicientcurrent passes through the instrument -.-.155, connection is completed through the-pointer 157 to the contact 156. The instrument 155'is adjusted to cause rotation of the pointer 157 much more rapidly than the pointer 19 of the instrument 17 is rotated, and if connection is made through the pointer 157 and the contact 156, the kick orrrelease coil 51 will be operated to open the switch 15, which will break the circuit through the battery. The pointer may be adjusted ito prcvent prolonged operation of the generator when acting as a motor to start the engine 2. As the current passes through the instrument 155, the conta t pointer 157 moves clockwise toward the cow tact 156 during an interim which is sufiieicnttopermitthe engine to start if under normal conditions. The time given in starting the motor may be varied by the stop adjusting arm 158 which may he turned to the right or to the left to reduce or increase the length of time that the engine may be turned by-the generator 3 acting as a motor. When the pointer 157 reaches the contact 156, the

circuit of the release coil 51 will he cone pleted from the instrument 1? which is connected with the positive pole of the battery through the lilies liialltl 18, and is completed to the battery through the lines 159, in strumcnt .155, pointer 15?, contact 156, line 48 and lines 47 and 2-), This will cause the switch 15 to open and break the circuit of the battery which is now ,iceding current to the generator 3 while operating, as a motor, whereupon the generator 3 will discontinue in its'ope'ration and the circuit of the battery will be left open.

If the engine starts before the pointer 15? reaches the contact 156, it will turn the armature of the generator. at a higher speed than it was previously turned while acting, as a motor and the current will be fed to thebattery through the line 150, the instrument155, the coulomb meterl7, the line 18, theswitch 15 and the line 16, the circuit being completed through the line 28, the contacts 122, 123, which are now closed, and the line 151. This will charge the storage battery. Inasmuch as the current, in charging the storage battery, passes in a direction opposite to that, in which it passes :while the battery is being discharged, in starting engine, the cnrrent through the instrument 155 will'cause the pointer lfiT'to'more coon terclockwise until it reaches the adjustable limiting arm 158, whereupon the pointer 15 will be held against the adjustable arm 15S and vill thus be in rcadincssfor a succeeding operation of the instrument 155. The pointer 19 ofthe instrument 17 will he retated clockwise toward the 100% battery charged point as the battery is being charged. i

The generator willnot only charge the storage battery, but it will also feed the consuming system having the' translating, devices. through a branched circuit, namely, through the lines 150, instrument 155, line 23, coil 24, lines 25 and 4, where the circuit branches and goes through the translating devices 8 and 9. lines 6 29, 28, contacts 12 122, and line 151, to the generator, and also through translating devices 7, linesfi and 26, contacts 124, 126. battery 160, line. 28, contacts 123 and 122, and line'151 to the generator 3. The lamps or other translating devices 7 are of a. form which require a potential. suhstantially the same as that of the battery 1, and inasmuch as the electro-motive force of thegenerator is higher than that of the battery, the counter-electromotive force of the cells 160 reduces the voltage impressed upon the translating de vices 7 located between the lines 4 and 5, while the translating devices 8 and 9 will operate on the higher potential produced by the generator.

\Vhile the generator is charging the ston age battery and the current is flowing through the line 151) and the instruments 155 and 17, lines 18 and 16, to the battery, the pointer 19 moves clockwise to the 100% battery charged point and makes contact with the contact 20' located on the point. This completes a circuit from the binding post of the instrument 1? which is connected l'hrouglrt'neinstrument 155 and the line 150 to the generator 3 and passes from the contact point 20 through the line 95, to the kick or release coil 59, and through the resistance coil 97, line 96, line 151, to the generator 3. The coil 59, which tends to produce polaritylin the switch 22 opposite to that produced by the coil 24, and the weight of the armature .75 cooperate to release the armature, causing the circuit of the coil 106 to be opened, the contacts 85 and 86 being permitted to separate by the downward movement of the rod 70. This re leases the core 112 oft-he master switch and permits the springs" 145 to open the circuit between the contacts 122 and 123,:an'd also opens the circuit heti'veen' the contact/5124 and 126, and r'eturnsthe switch to the position wherein the translating devices are fed by the storage hattery 1. J

In the operation or hesystem, assume that; the pointer 19"is;.aiti a fppi'nt intermediate. the contacts 20 an d 21,.whichcorrespond respectively to the 1QQf/0 and 85%l,battery charged points. v Asthe battery dig s'charged the current passing through the instrument 1? will cause the pointer to moretoward and finally make-contact the contact 21,. which will close the cirfcuit 'through the; (oil 56 to the bat-tery through the lines}? and 29, which willjcoactfwithfthe; coi1s24' and 7G, tl18 concatena it'd b ui jcmg mj from the batter hrough the raga-ups t 1?,

The master switch, when closed,w ill cause.

a current to flow from the storage'battery 1, throiwh the', line 150. the" generator 3, line 151, to the battery, and cause the generator to operate as a .motor to start the engine, which when started, will rotate the; armature of the generator 3 at 3 hi her speed, and generate a current which will flow through lines 150, 18 nnd is, to the battery 1, lines 28 and 151, unless the contact pointer 15? reaches the contact 150, in which case the switch 15 will be opened by the coil 51, producing a polarity opposite to that produced by the coil 50, the circuit being completed from the battery through the hnes 16 and 18, contacts 157 and 156, line 18, coil 51, and line 47. When the pointer 19' reaches the contact 20 or the 100% battery charged point the circuit will be completed from the terminal 53' to the kick or" release coil 51), thence to the generator which opens the circuit through the contacts 85 and 86 and the coil 106, which opens the circuit of the generator to the battery which is completed through the contacts 122 and 123, and restores the connection of the translating system to the battery 1, which is completed through the contacts 125 and 124.

If, however, the contact pointer 19 should pass the contact point 21 without causing operation of the automaticintercontrolling switch 22; the battery will continue to be discharged below the 85% battery charged point until it reaches the contact at the zero point, that is, until the contact pointer reaches the contact 52. The'eircuit will then be completed from the binding post 53 through the pointer 19, thecontactfil the lined 8, to the kick or release eoilfil. lines 7 and to the battery 1,' which will open the switch 15, andthus break the circuit of the battery 1 to prevent any damage thereto.

If anypart of the consuming system requires acurrent reatei than that that may be properlysupp ied b'yth'e battery 1,.sueh as direct the translatin ';devic'e's.8 or 9 lo cated intermediate thecries 1 and 6, it will on accountof the .increasedlwattage thus 40 consumed, cause theautomatic intercontrolling switch to be operated so as to close the contacts 8 5 and $6. The large current;'which atfthis time is passing through the line passes through the'current coil 2st of the automatic inter-controlling switch 22 and the increased ampere turns of the coil assisted by coil/7G cause the armature 74 to be lifted without the assistance ofthe coil 56 and start the generator 3, as heretofore described. that the system providesa means whereby current will be supplied by the generator if the watts eonsuniedis in excess of that which may be ordinarily supplied by the batterv. The generator will thus automatically talie upon Itself the loa djwhen the watts consumed is greater than that that can ordi narily be supplied. by the battery 1. Also. the battery may supply part of the current it the watts consumed is greater than that that can be supplied by thegencrator Also, the generator 3'may not only supply the current in the consuming system, but also charge the storage battery 1'. It the one 7 I rent which passes through the coil 21 is 0 large, the contacts 85" and 86 will be held closed by the magnetization produced by the coils 24 and 76, although the pointer 19 may be carried to the contact point 20 which completes the circuit through the release coil 59. The battery may continue to be charged until thelead' salt or oxide is be separated and further charging of the battery causes electrolysis of the water producing no useful work on the battery. When however, the current through the system containing the translating devices is reduced, and the cireuit through the coil 106 is opened to turn the load wholly upon the battery 1, the pointer 19' will immediately begin to move from the 100% battery charged point of the storage battery towards the battery charged point.

The releasecoil 59, being connected through the line 96 to the contact 122 of the master switch which is open under normal operation but is closed when there is an overload in the supplysystem, or when the battery is discharged to the 85%" point, prevents the counteraction of the coil' 59' when the overload is placed on the system so that the master switch will operate at once, even though the pointer 19 ot the amp'erehonr meter 17 stands at the full point, thatis, even though the pointer 19 is in contact with the contact 20. Itthe overload islsuddenly taken: ofl' of the supply system, the potential rises to a peak; increases the current through thecoil 59; which is in shunt conneetion in the circuitand permits immediate action of the automatic iritercontrolling switch 22to break the circuit through the coil106 of tliejiiaster; switch The circuit of the potential coil 56, being open at this time, does not ac-operate with the coil, 24. 7 so that the automatic intercontrolling switch 1 22 isfiminediately opened when the overload is removed, and the battery continues to provide the current for-the supply system.

Also takingth e' casefwherethe generator is running. having been started either by 1 contact at the 85% charging point 21', or by-a currentsupplyingpan overload and acting through coil 24,;the generator willicharge the battery untilpointer 19' is in contact with point If the wattage consumed by the. translating device's below a pred'eterminedamount (thisamount being fixedby what is considered a safe amount for the batteries to carry without the aid of the generator) the generator will be shut down throughthe action of coil 59 operating the master controller 22. If, however, the amt tage consumed by the translating devices is more than the above mentioned prede termined amount the master controller 22 will remain closed because the counteracting action of coil 59 will not be sufficient to overcome the action of coil 24. When the wattage consumed by the translating de vices is reduced suddenly or slowly, as for example'hy turning off one light at a time to the predetermined amount ,"'so"that the action ofcoil 24 nol'on'gei' overbzihinces the actionof'coil 59' but coil 59 becomes predominant then 'themaster controller 22 1s opened-and'the generator and engine are stopped. ":Whenit'is found desirable to start the charging ofithe battery,",'as for example, when the pointer 19 is' intermediate the 85% hattci y'chargetl'point and near the'danger or discharged point of the battery the pushbutton170, which'i's parallel with the contacts 19 and 21; is pressed, which completes a circuitffrom the line to the line 100,
